Define the concept of martingales in the context of this course.
Define the concept of martingales in the context of this course.
A martingale is a stochastic process with the property that, at any particular time in the realized sequence, the expectation of the next value in the sequence is equal to the present observed value.
Explain the significance of Itô's formula in the study of stochastic processes.
Explain the significance of Itô's formula in the study of stochastic processes.
Itô's formula is a fundamental result in stochastic calculus that provides a formula for the total differential of a function of a stochastic process. It is essential for deriving differential equations involving stochastic processes.
What is the role of Girsanov's theorem in finance and how is it relevant to this course?
What is the role of Girsanov's theorem in finance and how is it relevant to this course?
Girsanov's theorem is a key result in stochastic calculus that allows for changing the measure under which a stochastic process is modeled. It is important in finance for pricing financial derivatives and risk management.
